A major focus in conservation is acquiring forests – often at great expense – to expand the network of thousands of protected areas around the world. But conservationists cannot simply designate an area as “protected” and assume all species within the area will remain there, according to the study in Biodiversity and Conservation, which focused on a small Rutgers-owned old growth forest within William L. Hutcheson Memorial Forest in central New Jersey.
Though the forest could be considered ideal for many bird species because of its old growth status, nine species no longer nest there, the study says. These species, including the ovenbird (Seiurus aurocapilla) and American redstart (Setophaga ruticlla), were once common sights in the forest. Many other species have lower populations than would be expected.
“We argue that there must be a greater emphasis on monitoring and managing protected areas to achieve conservation goals,” said lead author Jeffrey Brown, a doctoral student and member of the Lockwood Lab in the Department of Ecology, Evolution, and Natural Resources at Rutgers University-New Brunswick.
